The condo has everything you will ever need, it's clean, well equipped and also located near a 7-11 and another small convenience store.
I wasn't actually planning on staying in the area of JJ market, but since my girlfriend lives there i moved there from the khlong toei sukhumvit area.
It is a bit more "local" than the expensive sukhumvit road, but it gives more of a "homely" feeling.
definitely would consider staying there again.
